SUMMARY OF INVENTION Technical Problem

FIGS. 17 and 18 are views illustrating an example of a conventionalcosmetics container. As illustrated in the schematic cross-sectionalview of FIG. 17, a container main body 100 includes a body portion 102and a connection portion 104. A cosmetic substance is held in the bodyportion 102. A gasket 110 is fixed inside the connection portion 104.The gasket 110 allows an applicator 120 to be inserted and withdrawn.The applicator 120 is configured with a shaft portion 122 and a brush124 affixed to the end thereof. The brush 124 is formed of a hairysponge-like material.

The gasket 110 has an inner peripheral surface 110 a and an uppersurface 110 b. The inner peripheral surface 110 a extends substantiallyvertically downward from the upper surface 110 b. The upper surface 110b is flat.

Meanwhile, in order for the user to use the cosmetics container forapplication comfortably, it is necessary to avoid situations in whichthe cosmetic material held in the cosmetics container stain the user'shands and in which the cosmetics container itself becomes soiled. Theconventional cosmetics container illustrated in FIG. 17 and FIG. 18 hasa problem where unless the applicator 120 is inserted from the directionin which the central axis in the longitudinal direction of the gasket110 extends (hereinafter, referred to as “central axis direction”), thebrush 124 hits the upper surface 110 b, the cosmetic material splattersand the cosmetic material adheres to the upper surface 110 b. In otherwords, as illustrated in FIG. 17, the brush 124 comes into contact withthe upper surface 110 b by merely shifting only slightly the directionin which the applicator 120 is inserted from the central axis direction.

In addition, in order to carry out makeup according to the intention ofthe user of the cosmetics container, the amount of the cosmetic materialadhered to the brush 124 and the position on the brush 124 at which thecosmetic material is adhered (for example, the tip and the center of thebrush 124) are important. For this reason, there are cases where theuser adjusts the amount of the cosmetic material loaded on the brush 124and the position on the brush 124 at which the cosmetic material isadhered (hereinafter, referred to as “fine adjustment”) by scraping thebrush 124 in the vicinity of the opening portion of the gasket 110.Specifically, as illustrated in FIG. 18A, the fine adjustment describedabove is performed by bringing the brush 124 into contact with a cornerportion where the inner peripheral surface 110 a and the upper surface110 b are connected to each other near the opening portion on the sideopposite the user's eye E1 (hereinafter, referred to as “corneredportion”) and moving the brush 124 outward as indicated by the arrow U1.When the brush 124 is scraped at the cornered portion, as illustrated inFIG. 18B, a portion of the cosmetic material 200 a loaded on the brush124 moves to the inner peripheral surface 110 a, but since the innerperipheral surface 110 a extends almost vertically downward, thecosmetic material 200 a quickly falls downward as indicated by the arrowD1. Since the inner peripheral surface 110 a extends almost verticallydownward from the upper surface 110 b, the user's eye E1 must look intothe inner peripheral surface 110 a, and since it is hard for light toenter the inner peripheral surface 110 a from the outside, it isdifficult to visually recognize the amount of cosmetic material withclarity. For this reason, it is difficult for the user to confirm howmuch of the cosmetic material 200 a has been scraped off. In otherwords, it is difficult for the user to grasp how much cosmetic materialremains on the brush 124. If the user has scraped off more thanintended, it is necessary to insert the brush 124 into the containermain body 100 and start the adjustment over again from the beginning.Furthermore, since the upper surface 110 b is flat, if the brush 124 isscraped at the cornered portion, a portion of the cosmetic material 200b remains on the upper surface 110 b so that there are cases where thecosmetics container itself may become soiled and stain user's hands.

The present invention has been made in view of the above and provides acosmetics container gasket and a cosmetics container that enable a userto use the cosmetics container more comfortably.

Solution to Problem

A first invention is a cosmetics container gasket in which an applicatorfor applying a cosmetic material is inserted and withdrawn, and which isdisposed at an opening portion of a cosmetics container main body inwhich the cosmetic material is held; wherein with the gasket, an openingend portion opposite to the cosmetics container main body is formed in aprotruding shape in a direction opposite to the cosmetics container mainbody; the portion between the main body portion of the gasket and theopening end portion is configured as a first inclined portion thatgradually increases in diameter from the main body portion toward theopening end portion; and the terminal end portion of the first inclinedportion is the opening end portion, and the diameter of the opening endportion is configured to be larger than the diameter of the outerperipheral surface of the wall portion configuring the main bodyportion.

According to the configuration of the first invention, the diameter ofthe terminal end portion (opening end portion) of the first inclinedportion of the gasket is configured to be larger than the diameter ofthe outer peripheral surface of the wall portion configuring the mainbody portion, and since the opening is wide, even if the user insertsthe applicator into the cosmetic container main body from a directionrelatively deviated from the center axis direction, as long as theapplicator is within the inside of the terminal end portion, theapplicator can slide along the first inclined portion and enter thecosmetics container main body. In addition, since a protrusion is formedin a direction opposite to the main body portion, that is, upward, evenif the applicator comes into contact with the terminal end portion, thecosmetic material does not remain in the terminal end portion, and evenif the cosmetic material does remain, the remaining amount is extremelysmall compared to the case of the conventional example in which theopening end portion is flat. The user scrapes the applicator with thefirst inclined portion or the terminal end portion to move a part of thecosmetic material loaded on the applicator to the first inclinedportion, but since the first inclined portion has a predetermined anglewith respect to the central axis direction, the cosmetic materialremains on the first inclined portion for a relatively long time. Sincethe diameter of the first inclined portion is greatly increased, due tothe relationship with the angle of the line of sight of the user (thesurface of the first inclined portion with the line of sight of the usertends to be smaller than 90 degrees), the first inclined portion on theside opposite to the user's eye is easy to visually recognize andexternal light enters more easily to improve visibility. For thisreason, the user can comfortably perform fine adjustment of the amountof cosmetic material loaded on the applicator with the first inclinedportion. As described above, the user can use the cosmetic containermore comfortably.

A second invention is the cosmetics container gasket according to thefirst invention, wherein a second opening end portion of the gasket onthe cosmetics container main body side is configured as a first cosmeticmaterial adjustment mechanism formed smaller than the outer shape of theapplicator; and the first inclined portion is configured as a secondcosmetic material adjustment mechanism formed such that the direction ofa line perpendicular to a tangent thereof approaches the verticaldirection toward the terminal end portion.

A third invention is the cosmetics container gasket according to thefirst invention, wherein the terminal end portion is configured as acurved surface.

A fourth invention is the cosmetics container gasket according to thefirst invention, wherein the outer portion of the opening end portion isconfigured as a second inclined portion inclined downward from theopening end portion.

A fifth invention is the cosmetics container gasket according to thesecond invention, wherein the inclination angle of the central portionof the second inclined portion is substantially equal to the inclinationangle of the central portion of the first inclined portion, or equal toor less than the inclination angle of the central portion of the firstinclined portion.

A sixth invention is the cosmetics container gasket according to thefirst invention, wherein the ratio (dC/dA) of the opening diameter dC ofthe opening end portion to the average opening diameter dA of the mainbody portion is 1.5 or greater and 1.6 or less.

A seventh invention is a cosmetics container comprising a cosmeticscontainer gasket according to any of the first through sixth inventions.

Effect of the Invention

According to the cosmetics container of the present invention, it ispossible to provide a cosmetics container gasket and a cosmeticscontainer which enable a user to use a cosmetics container morecomfortably.

DESCRIPTION OF EMBODIMENTS

Hereinafter, preferred embodiments of the present invention will bedescribed with reference to the drawings.

As illustrated in in FIGS. 1 and 2, a cosmetics container 1(hereinafter, referred to as “container 1”) comprises a cap portion 10and a cosmetics container main body 50 (hereinafter, referred to as“container main body 50”). The container main body 50 is an example of acosmetics container main body. In the container main body 50, a cosmeticmaterial such as mascara or liquid foundation is held. In the container1, the direction in which the cap portion 10 is located is referred toas an upper side (upper), and the direction in which the container mainbody 50 is located is referred to as a lower side (lower). The upperposition is expressed as “high position”, and the lower position isexpressed as “low position”. Further, the direction of the virtualcentral axis Z1 (hereinafter, referred to as “central axis Z1”) in thelongitudinal direction of the container 1 is referred to as the inside,and the direction away from the central axis Z1 is referred to as theoutside. The direction in which the central axis Z1 extends is alsoreferred to as the vertical direction.

The container 1 has a substantially columnar shape in which the diameternear both ends is larger than the diameter at the center portion. Themaximum diameter near one end is larger than the maximum diameter nearthe other end. The maximum diameter of the cap portion 10 is smallerthan the maximum diameter of the container main body 50. The container 1is large enough to be held by a user with one hand; for example, theentire length L1 of the container 1 is 130 mm and the maximum diameterW1 is 20 mm.

As illustrated in FIG. 3, the container main body 50 includes a bodyportion 52 and a connection portion 54. A male screw 54 a is formed inthe connection portion 54.

The shaft portion 40 is fixed to the cap portion 10. A brush 42 is fixedto an end of the shaft portion 40. The brush 42 is an example of anapplicator for applying the cosmetic material. The brush 42 is formed ofa hairy sponge-like material. Both ends of the connection portion 54 areopen, so that the shaft portion 40 and the brush 42 can be stored in thebody portion 52. That is, the brush 42 is inserted into and withdrawnfrom the container main body 50.

The lower end portion of the cap portion 10 is open to form asubstantially cylindrical concave space 10S. A female screw (notillustrated) is formed on the inner wall portion 10 a that forms aconcave space 10S and the cap portion 10 is made so as to be detachablyfixed to the container main body 50 by engaging with the male screw 54 aof the container main body 50.

As illustrated in FIG. 4, the gasket 20 is fixed inside the connectionportion 54 of the container main body 50. Note that in FIG. 4,illustration of the male screw 54 a of the connection portion 54 isomitted. The same applies to FIGS. 7 to 13. The gasket 20 is an exampleof a gasket for a cosmetics container. In addition, the upper endportion 40 a of the shaft portion 40 (see FIG. 7) is fixed to a space10S2 near the upper end of the cap portion 10 (see FIG. 7). The brush 42is made so as to pass through the gasket 20 when inserted into andwithdrawn from the container main body 50.

The container main body 50 is formed, for example, through injectionmolding of polypropylene (PP). The cap portion 10 is formed, forexample, through injection molding of polyethylene terephthalate (PET).The gasket 20 is formed, for example, through injection molding ofpolyethylene (PE).

As illustrated in FIGS. 5 and 6, the gasket 20 is formed in an overallcylindrical shape and includes a gasket main body portion 20 a and anenlarged diameter portion 20 b. The gasket main body portion 20 a is anexample of a gasket main body portion. Annular protrusions 20 a 1 and 20a 2 are formed on the outer peripheral surface 20 aa of the gasket mainbody portion 20 a and are made so as to be easily fixed to the inside ofthe connection portion 54.

The enlarged diameter portion 20 b includes an upper end portion(opening end portion) 20 ba, a first inclined portion 20 bb, a secondinclined portion 20 bc, a vertical portion 20 bd, and a lower endportion 20 be. The upper end portion 20 ba is an example of an openingend portion. The first inclined portion 20 bb is an example of a firstinclined portion. The second inclined portion 20 bc is an example of asecond inclined portion.

The gasket 20 is formed in a cylindrical shape in which the diameter ofthe upper end portion 20 ba is larger than the diameter of the outerperipheral surface of the gasket main body portion 20 a. The firstinclined portion 20 bb is configured to gradually increase in diameterfrom the inner side surface 20 ab of the gasket main body portion 20 atoward the upper end portion 20 ba. The terminal end portion of thefirst inclined portion 20 bb is the upper end portion 20 ba. The firstinclined portion 20 bb is configured as a curved surface portion that isconvex toward the direction of the vertical axis Z2 of the gasket 20.That is, the first inclined portion 20 bb is configured such that thedirection of a line perpendicular to the tangent thereof approaches thevertical direction toward the upper end portion 20 ba.

In addition, the upper end portion 20 ba is formed to protrude upward.Specifically, the upper end portion 20 ba is formed as a curved surface.The upper end portion 20 ba is located outside the outer surface (outerperipheral surface 20 aa) of the wall portion configuring the gasketmain body portion 20 a (see FIG. 6). That is, the diameter dC of theupper end portion 20 ba is larger than the maximum diameter dB of theouter peripheral surface 20 aa of the gasket main body portion 20 a. Theupper end portion 20 ba is configured as the uppermost portion which isthe highest position in the gasket main body portion 20 a. The upper endportion 20 ba is also an example of a terminal end portion.

The second inclined portion 20 bc is an outer portion outside the upperend portion 20 ba, is inclined so as to become lower toward the outsideand is configured to be lower than the upper end portion 20 ba. In otherwords, the second inclined portion 20 bc is inclined downward from theupper end portion 20 ba. The outermost part of the gasket 20 has amaximum diameter dD. The diameter dF of a lower opening portion 20 ac ofthe gasket 20 is slightly smaller than the diameter of the brush 42. Asa result, when the brush 42 loaded with the cosmetic material is pulledout from the gasket 20, excess cosmetic material is caused to drop atthe lower opening portion 20 ac of the gasket 20. That is, the loweropening portion 20 ac is an example of a first cosmetic materialadjustment mechanism for adjusting the amount of cosmetic materialloaded on the brush 42.

The inclination angle θ2 (the angle of inclination with respect to thevertical axis Z2) of the central portion of the second inclined portion20 bc is substantially equal to the inclination angle θ1 of the firstinclined portion 20 bb, or the inclination angle θ2 is defined to beequal to or less than the inclination angle θ1. In FIG. 6B, thedirection in which the vertical axis Z2 extends is the verticaldirection. In the present embodiment, the inclination angle θ2 is 20degrees, and the inclination angle θ1 is 35 degrees.

The ratio (dC/dA) of the opening diameter dC of the end of the firstinclined portion 20 bb (that is, the upper end portion 20 ba) to theaverage opening diameter dA of the gasket main body portion 20 a isdefined to be 1.5 or more and 1.6 or less. In the present embodiment, dAis 5.6 mm, dC is 8.4 mm, and the ratio (dC/dA) is 1.50.

As illustrated in FIGS. 7 and 8, the gasket 20 is pushed into theconnection portion 54, and the outer peripheral surface 20 aa of thegasket 20 comes into contact with the inner peripheral surface 54 b ofthe connection portion 54 and is fixed. The gasket 20 is fixed to theconnection portion 54 in a state where the lower end portion 20 be ofthe enlarged diameter portion 20 b of the gasket 20 is in close contactwith the upper end portion 54 c which is the upper end of the connectionportion 54.

Hereinafter, the state in which the brush 42 fixed to the shaft portion40 is inserted into the container main body 50 through the gasket 20will be described with reference to FIGS. 9 to 13. As illustrated inFIG. 9, the brush 42 may be inserted into the container main body 50from the direction of the extension of the central axis Z1 of thecontainer main body 50 (central axis direction), but as illustrated inFIG. 10, it may be inserted into the container main body 50 from adirection shifted from the central axis direction.

As long as the brush 42 is inserted from a position inside the upper endportion 20 ba of the gasket 20 (see FIG. 10), the brush 42 comes intocontact with the first inclined portion 20 bb (see FIG. 11), furtherslides along the first inclined portion 20 bb, (see FIG. 12) and isfinally inserted into the container main body 50 from the central axisdirection (see FIG. 13). That is, since the brush 42 is smoothly guidedfrom the upper end portion 20 ba to the first inclined portion 20 bb,the brush 42 is inserted into the container main body 50 withoutimpediment.

Next, a method for finely adjusting the amount of cosmetic materialloaded on the brush 42 will be described with reference to FIGS. 14 and15. As illustrated in FIG. 14A, the user performs fine adjustment usingthe first inclined portion 20 bb. The first inclined portion 20 bb is anexample of a second cosmetic material adjustment mechanism. The userfinely adjusts the amount of the cosmetic material by bringing the brush42 into contact with a portion of the first inclined portion 20 bbopposite to the user's eye E1 and moving the brush 42 outward asindicated by the arrow U1. That is, the user first passes the brush 42from which excess cosmetic material has been dropped in the loweropening portion 20 ac (see FIG. 6A) through the inner side surface 20 aband then pushes the brush 42 against the first inclined portion 20 bbsliding toward the upper end portion 20 ba and scrapes with the upperend portion 20 ba to drop unneeded cosmetic material or to perform fineadjustment such as adjusting the position on the brush 42 of where thecosmetic material is loaded. The user visually recognizes the amount ofthe cosmetic material that has moved from the brush 42 to the firstinclined portion 20 bb, and if the amount of moved cosmetic material isinsufficient, presses the brush 42 again against the first inclinedportion 20 bb to perform fine adjustment of the amount of the cosmeticmaterial. Since the upper end portion 20 ba is not flat, the cosmeticmaterial does not then remain on the upper end portion 20 ba.

Since the first inclined portion 20 bb has a predetermined angle withrespect to the direction of the vertical axis Z2 (see FIG. 6B), when theuser uses the brush 42 on the first inclined portion 20 bb to move, asillustrated in FIG. 14B, a portion of the cosmetic material 70 loaded onthe brush 42 to the first inclined portion 20 bb, the cosmetic material70 remains on the first inclined portion 20 bb for a relatively longtime. For this reason, the user is able to finely adjust the amount ofthe cosmetic material loaded on the brush 42 and the position where thecosmetic material is loaded on the brush 42 by using the first inclinedportion 20 bb like a palette used when painting a picture.

The inclination of the first inclined portion 20 bb is adjusted to anangle at which the cosmetic material moved from the brush 42 is easy tosee. Specifically, as illustrated in FIG. 15A, a tangent line at thecentral portion 20 bb 1 of the first inclined portion 20 bb is given asL11, and a line perpendicular to the tangent line L11 is given as aperpendicular line L21. A tangent line at the upper portion 20 bb 2above the central portion 20 bb 1 of the first inclined portion 20 bb isgiven as L12, and a line perpendicular to the tangent line L12 is givenas a perpendicular line L22. Note that the tangent lines L11 and L12 areillustrated slightly away from the first inclined portion 20 bb forexplanatory convenience. Assuming that the angle between theperpendicular line L21 and the horizontal line L3 is an angle θ11 andthe angle between the perpendicular line L22 and the line L3 is an angleθ12, the angle θ12 is larger than the angle θ11. That is, theperpendicular line L22 is closer to the vertical than the perpendicularline L21. Therefore, as illustrated in FIG. 15B, when the user's eye E1visually recognizes the central portion 20 bb 1 of the first inclinedportion 20 bb with the line of sight in the direction of theperpendicular line L21, in the portion above the central portion 20 bb1, external light from the direction of the perpendicular line L22 istaken into the first inclined portion 20 bb closer to the vertical thanthe perpendicular line L21 or the direction of the perpendicular lineL23. Since the first inclined portion 20 bb is expanded so as to have alarger diameter than the gasket main body portion 20 a, due to therelationship to the angle of the line of sight of the user's eye E1, thecosmetic material 70 (see FIG. 14B) resting on the first inclinedportion 20 bb on the side opposite to the user's eye E1 is easy tovisually recognize. That is, viewing of the cosmetic material 70 (seeFIG. 14B) attached to the first inclined portion 20 bb inclined in thedirection of the line of sight of the user's eye E1 as illustrated inFIG. 15B has better visibility than with the case of viewing thecosmetic material 200 a resting on a wall portion nearly perpendicularto the line of sight of the user's eye E1 as in the conventional exampleillustrated in FIG. 18B. In addition, since the diameter of the firstinclined portion 20 bb is enlarged so as to have a diameter larger thanthat of the gasket main body portion 20 a, a shadow is less likely toform and external light is more likely to enter so as to improvevisibility.

For this reason, the user can comfortably perform the fine adjustment ofthe amount of cosmetic material loaded on the brush 42 on the firstinclined portion 20 bb.

Second Embodiment

A second embodiment will be described with reference to FIG. 16.Descriptions of items common to the first embodiment are omitted.

In the gasket main body portion 20A of the second embodiment, the ratio(dC/dA) of the opening diameter dC of the end of the first inclinedportion 20 bb (that is, the upper end portion 20 ba) to the averageopening diameter dA of the gasket main body portion 20 a is smaller thanthe gasket main body portion 20 of the first embodiment. In addition,the inclination angle θ2 is equal to the inclination angle θ1.

The cosmetics container of the present invention is not limited to theabove embodiments, and various changes can be made without departingfrom the gist of the present invention.
